The Document Processing Module

The Document Processing module processes image files supplied via a document input, performs file format conversions and – depending on the file type selected – also performs OCR recognition. Without this module, the destination file is always the TIFF file generated by the document input from the supplied image file.

The module cannot process PDF files.

The module can occur several times in the workflow.

Image enhancement module

The module can be connected to all modules (this can result in nonsensical workflows).

No restrictive modules.

Destination file format into which the supplied file is to be converted.

  • JPG
  • XPS
  • PNG
  • TIFF
  • PDF - PDF file contains JPEG image with configurable compression.
  • PDF (image) - PDF file contains TIF image with configurable compression.
  • PDF/A (image) - PDF/A compliant file contains TIF image with configurable compression.
  • hcPDF - High compression PDF.

OCR formats (non-license-free OCR formats are only selectable on the device if the device has an OCR license, see also OCR and barcode recognition)

  • Portable Document Format (pdf)
    • PDF TS (OCR + image) (license-free OCR with Tesseract)
    • PDF/A TS (OCR + image) (license-free OCR with Tesseract)
    • PDF/A (OCR only)
    • PDF/A-1b (OCR only)
    • PDF/A-2b (OCR only)
    • PDF/A-2u (OCR only)
    • PDF (OCR + image)
    • PDF/A (OCR + image)
    • PDF/A-1b (OCR + image)
    • PDF/A-2b (OCR + image)
    • PDF/A-2u (OCR + image)
  • Word (doc) OCR
  • Word (docx) OCR
  • Excel (xls) OCR
  • Excel (xlsx) OCR
  • PowerPoint (ppt) OCR
  • PowerPoint (pptx) OCR
  • Rich Text Format (RTF) OCR
  • Text (txt) OCR
  • Off: File separation is switched off, all pages scanned together in the document feeder are stored in one file. This does not work if the file format cannot contain several pages or with any image formats (e.g. TIFF, JPG).
  • Number of pages: File separation is active and saves the specified number of pages in one file (e.g. if 6 pages are scanned and 2 pages is selected, this results in 3 files with 2 pages each). B/W TIFF documents are compressed using LZW.

JPEG quality lets you specify the quality of JPEG files embedded in PDF files. Consequently, this setting only affects PDF files. This setting also allows you to influence the size of the resulting PDF file.

The higher the quality percentage, the larger the resulting file will be (not proportional).

  • 50%
  • 75%
  • 90%
  • 100%

Similar to the Combine function when copying, this function allows two pages to be scanned vertically and reduced in size to a landscape page.

  • Off: Two on One is off, the pages remain unchanged.
  • On: Two pages are displayed vertically and reduced in size on a landscape page side by side.

The PDF file format allows a file to be password protected. This setting is ignored for other file formats. The password is required to open the PDF file.

  • Password: If the PDF file is to be password protected, enter the password here. The content of the password can also come from a variable (e.g. from zone OCR or from XML file transfer).

According to the PDF definition, password protection is not possible for any archive formats (PDF/A...).

The ImageService processes image data (e.g. from scans) and performs file format conversions, image optimization and the OCR function. It stores files in desired destination directories (depending on the module used, the rights of the user executing its application pool are used for this purpose). Its log file is Logs\ImageService.log.
